How to Tag friends in Your Facebook profile uploaded Photos | Tag someone in your photo – Tagging friends in your uploaded photo is like you creating a link to their own profile. When you tag someone in a photo, that person’s friends may also see, like or comment on the photo.

Also, if you tag a photo that was not uploaded by a friend, the person who uploaded the photo will need to approve the tag. So tagging people in your photo, is just like you getting them to know other people tagged in that same photo.
